It’s unclear what caused the fighting. However, EAA’s interim chancellor, Veronica Conforme, referenced gang violence in a statement to the newspaper.

“I am appalled by this act of violence in a place of learning. Gang violence is a serious issue in our city and we must all come together to eradicate this problem,” she said in the statement.

The EAA, the state’s turnaround district for low-performing public schools, contracts with Detroit Public Schools police to provide some services. The district also utilizes a private security firm.
